Three RCTs showed that rubber band ligation was better than injection sclerotherapy in a variety of outcomes (pain, repeat treatment, prolapse, bleeding) in persons with mainly second-degree hemorrhoids; however, rubber band ligation was associated with more immediate adverse effects.
Edema is the medical term for swelling. Body parts swell from injury or inflammation. It can affect a small area or the entire body. Medications, infections, pregnancy, and many other medical problems can cause edema. Edema happens when your small blood vessels become leaky and release fluid into nearby tissues.
Edema is the result of damage to capillaries or increased pressure causing capillaries to leak fluid into surrounding tissues and result in swelling. People with diabetes often have circulation problems that can cause wounds to heal slowly or not at all. Edema makes it more difficult for wounds to heal.
